I have a few components that would create a reasonable PC, 1.5 processor, nVidea BFG card, spare HDD but I'm missing a few things like a PSU and RAM sticks, all peripherals. It'd also mean installing an OS and finding all the correct drivers before 23rd May too.... I don't think I could commit to that as all my spare time is taken up with wedding stuff at the moment.
The lappy sounds the best option, get Aggs Steam login installed on there, pre-install L4D... would it run Civ? PoE is scaleable isn't it? Plus we can setup some of my old games I've been looking at on there as well as Megadrive emulator for 2 player Streets of Rage

(I have this)
